Since Python3.13 upgrade there are many deprecation warnings from packages. These are not my concern, I'm sure the maintainers will sort things out by the time they need to. If they don't it won't be a warning and I'll see the error.

Found a number of forum posts on how to suppress DeprecationWarning using different methods, none of which worked in current version of pytest.

This syntax in pytest.ini seemed like a fairly succinct way to suppress all DeprecationWarning messages, but it didn't.
Forgot about the change that did nothing at the time.
After Python3.13 upgrade pytest crashed every time.

Eventually found it was this filterwarnings line:

[pytest]
minversion = 6.0
addopts = -ra -q
asyncio_mode = auto
asyncio_default_fixture_loop_scope = function
testpaths =
    tests
filterwarnings = ignore::DeprecationWarning:*

It might be that this is invalid syntax edge case, in which case the line can be ignored with an appropriate (non-fatal) error message.
What would be terrific is if it actually did suppress all DeprecationWarning messages, as the syntax suggests.

Crash is easily reproduced:

You're asking for modules matching the regex r"*" this regex is invalid because of the reasons in the traceback.

You should simply omit the module to match any:

filterwarnings = ignore::DeprecationWarning

The invalid pattern is clearly an user error and shouldn't just magically work, but I agree that the error message could be more readable.

#12526 did something similar for pytest.raises for some inspiration. @virendrapatil24 do you maybe want to pick this one up too?
